There is no bond stronger than the one between siblings. Yui has been the center of her brother's sexual desires ever since they were children. But in recent years, something in their relationship has changed. The divorce of their parents has forced Akira to pay more attention to Yui's well-being, take care of her on a daily basis, and assume the paternal role in their family.

As the two grow older, Akira has taken notice of the physical changes in Yui—she is no longer the precious child he thought he knew. Unable to stop himself, he starts sneaking into her room at night, admiring his sister's body and pleasing himself to her. Akira becomes increasingly frustrated with the distance between them; but when Yui reveals that a friend from school has confessed to her, something snaps inside him.

No longer restricting himself to mere daydreams, he actively has intercourse with his sleeping sister. However, unbeknownst to Akira, Yui remains wide awake during these nightly visits; yet, for some reason, is unwilling to stop him.

Art: Art is good. After 2nd episode it will be better. Overall I liked it. Good Character designs, details, voices, sounds. It is more than enough.

Scenes: About scenes. Until the first sex scenes are so so. After first sex scene at the end of 1st episode, scenes start to improve. And one point. It is about having sex while sleeping. I mean the sister pretends she is sleeping until some point in the story.

Non-sense: There are no anal sexes, sick stuff, force sexing which is really good, ...

Story :
I very like this anime story. I've watched it many times. When i watch this anime, i feel nostalgic because I've experienced something like that in my life. Not 100% similar, maybe only 70% similar with my personal stiry. .That's why i very like this anime.

This anime art is great for a hentai anime. the animation movement is also not stiff, the point of view when doing the "nice thing" is also quite good.

The anime backsound is really good. The ending song is good too, this is probably the first hentai anime song i've ever heard until end when i watch the ...

Preliminary (2/4 eps)
The story is about a boy who takes care of his younger sister after the death of his father. Their sibling relationship worked well until his sister told him there is someone to whom she felts love. For that, the boy becomes jealous and from next night he regularly starts rape his sister with presumption that she sleeps and doesn't realize it. Brother and sister's sexual life just begun.

First thing you should know is that I don't like anime titles with same or similar story. If it's just a side storyline and it's processed well, I don't have a problem with it, but when it ...
